Your product gets great reviews, and the testing videos I've seen pretty much say it all.

Was looking on Amazon and it was an estimated time of 6 weeks, came here straight and hust ordered off the website instead and it took only 3 days to get from the states to Toronto, was also about 60$ cheaper then amazon

Fantastic filter. Fits perfectly in my 2025 Ford Maverick. Already can tell there is better air flow and some increase in fuel mileage. Just need to get the cleaner and oil for when that time comes. Also glad it's made in my state of Pennsylvania.

Not sure how its supposed to filter when you can see small holes in the filter media.
